Warning lights for road safety

Abstract

The invention relates to the technical field of road safety, and discloses an alarm lamp for road safety. The alarm lamp comprises a solar battery panel, a lamp box and a support shaft, and the two inner sides of the lamp box are each provided with sliding cavities in the width direction of the lamp box; a water cavity is arranged between the two sliding cavities; each sliding cavity is internallyprovided with an alarm unit comprising an LED lamp, a lamp panel and a lens shade used for light concentration of the LED lamp; the lamp panel is fixedly provided with a pressure spring and a slidingrod, and the sliding rod is fixedly provided with a sliding plate located in the water cavity; the sliding plate of one alarm unit is provided with a button switch which can be pressed by the slidingplate, and the sliding plate is provided with a water channel; the sliding plate of the other alarm unit is provided with a push rod; the water cavity is fixedly provided with a heater located between the two sliding plates, and the water cavity communicates with outside through a reversing valve; when the push rod is pushed, the reversing valve is reversed; and the lamp box is provided with a main pipeline communicating with an auxiliary pipeline. The alarm lamp is simple in structure, and the dust prevention of the LED lamp can be achieved, and the radiation distance of the LED lamp can befurther increased.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to a warning light for road safety. Background technique [0002] Warning lights are generally used to maintain road safety, especially on expressways. As more and more vehicle failures on expressways occur frequently, warning lights can effectively prevent or avoid car accidents on expressways. [0003] Existing warning lights include light boards, electronic display screens installed on the light boards, and solar panels that provide electricity. During the daily use of warning lights, passing vehicles will cause the warning lights to adhere to a lot of dust and impurities. Dust and Impurities can hinder the light irradiation effect of the warning light. In order for dust and impurities not to affect the light irradiation of the warning light, it is necessary to clean the warning light. The existing cleaning method is manual cleaning, but the warning lights are installed at ...

AI Technical Summary

Problems solved by technology

The existing cleaning method is manual cleaning, but the distance between the installation of warning lights on the expressway is relatively large, which is inconvenient to clean, so it not only wastes time but also consumes a lot of labor.

In fact, the rain in rainy days can wash away the dust and impurities on the warning light, but because too much rainwater attached to the warning light will affect the light of the warning light and make the light weaker, so a rain shield will be installed on the warning light , and the flashing will block the rain so that the warning lights cannot be washed

[0004] Secondly, the rain in rainy days will actually make the light of the warning lights dim, making it difficult for the naked eye to see clearly. This is one of the reasons for frequent accidents on the highway in rainy days.
